No lawmaker in Congress should be able to buy, own, and sell individual stocks. Period. Let's make Congressional stock trading illegal.

Ask an expert: How can I manage my type 1 diabetes? Approximately 300,000 Canadians live with type 1 diabetes, an autoimmune disorder with no known cure. Type 1 diabetes can pose serious challenges, but ongoing research is improving the quality of life for those with this chronic condition. Endocrinologist Dr. Breay Paty discusses the effects of low and high blood sugar, as well as science-backed management strategies and emerging biological treatments for type 1 diabetes.

This #WorldDiabetesDay, discover the effects of low & high blood sugar, as well as science-backed management strategies & emerging treatments for type 1 diabetes from VCHRI expert Dr. Breay Paty:

Restoration of pancreatic beta cell identity and autophagy in KATP-induced diabetes by intermittent fasting - Diabetologia Aims/hypothesis The loss of pancreatic beta cell mass and identity is a hallmark of diabetes. While factors such as beta cell overwork (insulin hypersecretion) and elevated intracellular calcium have been implicated, beta cell identity loss also occurs in KATP gain-of-function (KATP-GOF) mice, a model of human neonatal diabetes, even in the absence of these factors. This suggests additional underlying mechanisms. Autophagy, a key process for cellular homeostasis, is impaired in the islets and beta cells of both type 1 and type 2 diabetes, but its role in monogenic diabetes with insulin secretory deficiency remains unclear. We hypothesise that autophagy dysfunction contributes to beta cell identity loss in KATP-GOF mice, and that intermittent fasting (IF) can restore autophagic flux, thereby preserving functional beta cell mass. Methods To test this, adult tamoxifen-inducible KATP-GOF mice and littermate controls were randomly assigned to two groups: (1) chow diet ad libitum; and (2) chow diet with alternate-day IF. Results KATP-GOF mice fed ad libitum developed severe hyperglycaemia due to impaired insulin secretion. This was followed by a reduction in insulin content, disruption of beta cell autophagic flux, autophagosome accumulation and, ultimately, the loss of beta cell identity and dedifferentiation. In contrast, KATP-GOF mice subjected to alternate-day IF exhibited lower blood glucose levels, improved mitochondrial morphology, restoration of autophagic flux and reestablishment of beta cell identity. Conclusions/interpretation This study provides the first evidence of autophagy impairment in non-obese, insulin secretory-deficient, KATP-induced diabetes mice and demonstrates that IF restores both autophagic flux and beta cell identity. This finding suggests that similar mechanisms may contribute to beta cell dysfunction in other forms of diabetes. Graphical Abstract

Based on studies of autophagy in non-obese, insulin secretory-deficient KATP-GOF mice the authors propose that #IntermittentFasting prevents the gradual loss of beta cell identity by enhancing autophagy link.springer.com/article/10.1...
